Horrible service

On the 3rd of March bought a set following day when Im preparing to wear the other bra I notice its faulty. Mind you toke out the tags and threw away the slip as this is not my first time purchasing at edgars. then the 6th I go to the store to return the one bra Eunice says I cant return it as I dont have a slip then she leaves me for 10 minutes to find out from the lady that works in the underwear dpt to find out if its possible, comes back then tells me I must come with the other bra I ask why because its only 1 bra thats faulty not the other she says I bought them as a pack. I call their complains department they tell me the query will take 48 hrs give them my details to tell me the conclusion.fast forward to the 13th they tell me the store has been calling me I ask which nos they tell me my cell no which I specifically said they must call me on my work number. on their notes theres no other feedback about what do I do about the faulty bra. then on the 17 wen I call again they tell me Im not co operating as if like im their child mna. Im going back and forth with the complains department which proved to be useless as it did not help. Im stark with a bra I wont wear. ********** SERVICE FROM WESTGATE STORE IN ROODEPOORT
